Sample Size Calculator

Testing is a big part of marketing. If you don’t test, you’re just guessing. Test your direct mail, test your email and test your telemarketing. But how many people should you include in your test?

If you test your ideas with a very small number of people the results may not be statistically accurate. As a result, you might roll out a campaign that does not reach its full potential or fails.

On the other hand, testing ideas against a large number of people can be expensive.

For confidence in your test results we have created a Sample Size Calculator. This will give you the right number of people to include in your test. Use it for telemarketing, direct mail or email marketing.
